The Judo club I have attended seem to go hard in Randori. I am training for fun, fitness and self defense but have not sparred yet. Is it appropriate to ask other players to go easy on you? I image they would anyway but I really can't jeopardise my job with injuries.
The other guys should respect your grade when they are sparring with you. Your instructor should ensure you are partnered with people who are sensible. If you get partnered with another beginner however...
Yeah, just ask them to go light. If they still go hard you have every right to stop sparring with them there and then.
No one who's not a pleb should have any problem with you asking. Its only ever an issue when people ask that and then go full power themselves. People are aware others have commitments outside of lessons and that others will have different goals and comfort levels. There's absolutely nothing wrong with requesting to take it easier.
I've asked people to go easy in sparring before. There's no shame in it and nobody I've met has a problem with it either.
Don't stress about sparring. It's not good practice to injure your training partners, or you soon run out of people to train with. I find it's other beginners who go the hardest, get partnered with an experienced guy with nothing to prove, they will go easy on a new guy. Another beginner though it will turn into a competition, not training.
Of course, but remember if you lock out and muscle things they're more likily to match you intensity, learning to relax and get thrown is a skill in itself.
